Some churn is normal — and even healthy. But a rising unsubscribe rate is a signal your strategy needs a rethink. Mailpro measures it for every campaign, so you can spot the trend early and act on it.

The newsletter unsubscribe or cancellation rate is measured when someone leaves your list. Some churn is predictable — and unsubscribes actually help keep your mailing list healthy. But a high rate shows your strategy isn't working. People typically unsubscribe because they receive too many emails, the content feels irrelevant, boring or repetitive, they simply don't want your newsletter, or the images are poorly designed.
With Mailpro you can measure the unsubscribe rate of every campaign, analyze the reasons behind it, and re-think your approach before it hurts your open rate and deliverability.
Calculating it is simple: divide the total number of unsubscribes by the number of newsletters delivered. If a campaign of 4,000 emails has 30 unsubscribes, your rate is 0.6%. Anything below 0.5% is considered good; above 0.5% points to a problem you shouldn't ignore. Tracking it regularly helps you realign your strategy.
Open rate, click-through, deliverability and unsubscribe rate are all different views of the same campaign — and each affects ROI, revenue per email and order value. Mailpro's simplified unsubscription management keeps opt-outs off your list automatically.
